Oil Seals: Enablers for optimum industrial sealing

Oil Seals
Oil seals are used to prevent leakage of sealed objects such as lubricants from inside and also for preventing the entry of dust and contaminants from outside. Oil seals are named as such because they use oil itself as the sealing medium. Sometimes these are also referred to as fluid, dirt or grease seals. An important part of pretty much all types of machines and also running vehicles, these can protect almost all types of precision constructed, close fitting ball, sleeve, roller bearings etc.

Oil seal manufacturers typically design these in a variety of shapes according to the application area and also substances that are to be sealed. Furthermore, these are designed in such a way so as to ensure their optimal suitability to environments ranging from normal to the most severe. Another noteworthy thing here is that oil seals can also be customized based upon any specific requirement. 

Application areas of oil seals:

These seals are helpful in a full range of equipments that are used in various sectors such as,
  •     Automotive
  •     Manufacturing
  •     Oil refineries
  •     Power transmission
  •     Off-highway

Types of oil seals:

Since oil seals are used across various industries, as a result these are available in innumerable types. Some examples are,
  • Commercial vehicle oil seals – These consist of rubber ribs that will cover the whole axle shoulder, sealing around grooves and nicks. The running surface of the seal is even and flexible , which allows for the seal to move from side to side if need be
  • O-ring seals – These seals are used in in almost all operating vehicles, from motorcycle ATV's to construction equipments
  • V-seals – These generally consist mainly of rubber, making these easy to mount. V-seals are perfect for retrofitting
  • Pressure resistant seals – The are specifically designed to reduce lip deformation caused by oil pressure
  • Mud-resistant seals with integrated sleeves – The distinguishing feature of these seals is that these are designed to enhance the prevention of entry of mud
Manufacturing of oil seals:

Apart from rubber, oil seals can also be made out of several compounds and materials, such as :
  •     PTFE
  •     Tetrafluoro-ethylene-propylene
  •     Fluoro-elastomer
  •     Silicone
  •     Polyacrylate
